CARTGFsl-SEJLLlIZ-IG To all whom it may concern:

Be it known that 1, hi Barium a citizen of the U2 .eed States, residing at Battle Creek, count of Calhoun, State of hiichigan, have ii Tented certain new and useful Improvements in Carton-Sealing Machines, of which the following is a speoification.

This invention relates to improvements in Carton sealing machines.

The main objects of this invention are:

First, to provide in a carton sealin chine an improved means for supporting the flaps to insure the even application of glue thereto.

Second to provide in carton sealing inrehine an iinprored means for suppoitn carton flaps as they are acted upon by [-1 glue rollers so the the cartons are not likely to be distorted during the o eration.

Third, to provide in a carton sea chine an improved means for apply g e glue to the flaps which is eeonomieal in lie use of glue.

Further objects, and object I accomplish the objects of D1; by the devices d means deseribed in the following speti cation. The inrentien is 1 w 1. i U clearly defined and pointed out in b119, claims.

Fig. V is a detail section on a line corresponding to line 5-5 of Fig. I.

F V1 is a detail View partially in sec tion on a line torresponding to line 66 of Jigs. .l and II, showing details of the con- In the oraiiing similar reference characters refer to similar parts throughout the sereral views, and the sectional views are up folder 5 mounted on the shaft 6 above conreyer. The front flap is folded downwardly upon the folded rear flap by th tfillJOllS passi g under the flap folder an spreader 7. This front flap folder and spreader is designed to fold the front upon the previously folded rear flap ant. spread the side flaps 8 of the carton 4 out\ L- dly. At the rear of this flap spreader are glue wheels 9 which reeive their glue driren from th shaft 11 having a driving gears 13 and 14 to the glue rollers. flap spreader has a rearward platelilze exten ion 15 and while still retained in their spread position the flaps are engaged by the flap supporting and pressing plates 16 carried by the hains 17. These chains are supported by the sprockets 18 and 19, the sproke s 19 being the driving sprockets and carried by shafts 20. These shafts are supported by bakets 21 projecting inwardly from the frame so that the cartons may pass between as shown in Fig. I. As the flaps 8 supported by the plates 16 pass from the retaining members 15 they travel under the glue rollers 9.

To support the upper reaches of the chain 17 and yieldingly press the flaps against the glue rollers I provide the bars22 Whichare ape are folded forwardly by the osfillating i the troughs 10. The glue wheels are Cir disposed between the sprockets to support the upper reaches of the chains, as shown in Fig. II. These bars are yieldingly supported by springs 23 and the pins 2th carried by arms 25 projecting from the sup porting brackets for the sprocket wheel shaft.

The shafts 20 are connected to the jack shaft 26. by means of sprockets 27 thereon and sprockets 28 on the shafts 20 and the sprocket chains 29. The ja ck shaft 26 has a driving clutch member 30 rotatably mounted thereon and driven from the chain 31 and a roacting driven clutch member 32 keyed to the shaft.

The driven clutch member carries a spring actuated engaging member 33 which projeets therefrom in position to be engaged by the releasing member 34: carried by the pivot shaft 35 which is shown in Fig. I in its retracted position. The clutch engaging member is actuated by spring 36 so that normally the clutch is engaged. When, however, the releasing member 34: is in its normal or clutch releasing position the clutch engaging member 33 comes into contact therewith as the clutch rotates thereby releasing the clutch. The releasing member is actuated from the rock shaft 37 having a trip arm 38 thereon adapted to be engaged by the cartons as the are carried along by the feed conveyer which actuates the releasing memher so that the clutch engaging member passes on each revolution of the clutch providing a continuous drive for the jack shaft until a holder having no carton thereon passes the arm when the clutch is released until the rock shaft is again actuated to actuate the releasing member.

The holders have notch-like recesses 39 to permit their passing the arm 38 without actuating the same when no carton is present. The rock shaft 37 is provided with an arm 40 connected to the release member 34 by the link 41. A spring 42 connected with the arm 40 and to the frame returns the release member to its releasing position.

lVith the parts thus arranged the flaps to be glued are firmly pressed against the glue rollers at the same time their supports traveling with the conveyer prevent their being distorted or twisted on account of such pres sure. By thus supporting and pressing them against the glue rollers a thinner glue and a less quantity of glue is sufficient to properly secure the desired adhesiveness than is necessary otherwise, so that my improvements result in a saving of glue and, further, the thin small quantity of glue sets quickly. By driving the flap supporting means only when cartons are present, the supporting plates pass the glue rollers only when protectedby the flaps so that they do not be c ome'touled withthe glue which would seriously interfere with the practical operation of the machine.

I have not shown means for closing and sealing the flaps after the glue is applied thereto as such means form no part of this invention. T have not attempted to illustrate or describe various adaptations and modifications which I contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

l l aving thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
